WILLIAM OTTO WEISSIOH, OF SAN FRANCISCO, CALIFORNIA.

REGISTER FOR TELEPHONES. L

Specification of Letters Patent.

Application filed December 29, 1906.

Patented April 27,1909. Serial No. 350,041.

To all whom it may concern.-

Be it known that I, 'WILLIAM O'r'ro VVEIssIoH, a citizen of the UnitedStates, residing in the city and county oi San Francisco, in the Stateof California, have invented a new and useful Register for Telephones,oi which the following is a specification.

My invention is designed for the purpose of registering telephone calls,and, more particularly, for registering them in such a manner as torovide an accurate record, at all times, of t e tolls due from any givenstation. Thus, the necessity for depositing a coin in the slot may beobviated.

The'object oi'my invention is to provide a device of the above naturewhich shall be accurate and reliable, and at the same time, simple andefficient.

In order that my invention may be readily understood, reference is hadto the accompa nying drawings, forming part of this specification, andin which Figure 1 is a perspective view of a telehone box equipped withmy invention. ig. 2 is a front elevation on an enlarged scale, of theregistering mechanism, the casing being in section. Fig. 3 is a similarview, showing the parts in a different position.

Referring to the drawings in detail, A represents a telephone wall setof any usual or desired construction. To any convenient Bart of thisinstrument is attached a casing containing the registering mechanism.This mechanism comprises a registering device or counter, O, mounted inthe lower part of the casing, and which may be of any ordinary ordesired construction, as it forms no part of the present invention.

Mounted above the registering device is a plunger D, arranged toreciprocate vertically, and having its upper end projecting through thetop of the casing. This plunger comrises an upper portion, provided witha colar t, and lug n, and terminating at its lower end in an annularflange H, and a lower portion or shank, depending below this flange H,and passing through a fixed guide E, secured to the casing. A coilspring J, surrounds the shank, and, bearing between the guide E andflange H, normally holds the plunger in its upmost position, as shown inBig. 2.

A magnet I, is mounted in the casing, and is connected, by means ofwires g, g with the central ofiice. An armature, G, is pivoted adjacentthe magnet, and formed at its lower end with a hook, 8, arranged tonormally coo erate with the flange H, and thus lock the pliinger in itsupper position.

The plunger D is formed on one side with a series of notches, or ratchetteeth, Z, and arranged to cooperate therewith is a pivoted pawl K. Thispawl is provided, adjacent its pivot with a specially formed head, w,formed with two faces, '1, r, disposed at an obtuse angle with eachother. A leaf spring 'm, is secured to the casing, and bears againstthis head, resting, as shown in Fig. 2, some times against face r, and,as shown in Fig. 3, sometimes against face 1 When in the position shownin Fig. 2, the pawl is held resiliently so as to engage the ratchetteeth, and when in the position shown in Fig. 3, the pawl is held awayfrom the teeth. The s ring m, connects with a binding post on t ecasing, and a second binding post con nects by means of a wire 0, withthe frame of the registering device O. A circuit, 0, g, connects thesebinding posts with a signal p, such as a lamp, at the central ol'lice.An operating button F, for the registering device O, is located directlybelow the plunger D;

The operation. of my invention is as follows: A party wishing to make acall, calls 11) the central olfice in the usual manner. The operator,then, instead of requesting the party calling to deposit a coin,requests him to depress the plunger and thereby operate the registerindevice. At the same time, the operator 0 oses the circuit g, g, andenergizes magnet I, thereby withdrawing hook, s, and permitting theplunger to be depressed. Thus it will be seen that the registeringdevice cannot be operated exce t by permission of the central. When theplunger is depressed, its lower end contacts with button F, thusactuating the registering device, and recordin the fact that a call hasbeen made. At the same time, the circuit 0, g, is closed at F, and theoperator is thus advised of the fact that the register has beenactuated. Obviously, the operator will not make the desired connectionuntil the signal p, gives its indication that the register has beenactuated. The register may be read by the arty calling, by means of theopening R, ormed in the casing B. The ratchet teeth Z and awl K, preventincomplete actuation oft e lunger. The awl catches, in each succee ingtooth, as t e plunger is depressed, and revents a return stroke, untilthe end of t e down stroke is reached,

Cir

when the lug n throws the pawl K to the position shown in Fig. 3,, thusdisengaging it i from the teeth, and permitting the return of l theplunger. Near the end of the return l stroke, the end l flange H asshown in Fig. 2, and moved into operative 1position for the next stroke.It will t us be seen that I have provided a very simple, i

for the purpose described, and it is thought the numerous advantages ofmy invention will be readily appreciated by those skilled i in the art.1

of the pawl is engaged by the reliable, and convenient device What Iclaim is 1*- 1. A registering attachment for telephones comprising alocal registering device, a plunger operated by the subscriber forpositively actuating the same, a lock normally preventing any movementwhatever oi' the plunger in a direction to actuate the regis teringdevice, and a magnet for releasing said i look, said magnet being in acircuit controlled l wholly by the central 0 erator.

2. A registering attac iment for telephones comprising a registeringdevice, a spring pressed )lunger i'or ositively actuating the same, alatch normally engaging and locking said plunger against movement in adirection to actuate said registering device, an electro- I magnet incooperative relation with said latch, and a circuit for saidelectromagnet i controlled from the central ofiice. i

3. In an apparatus for registering telephone calls, a registering deviceat the subscribers station, local means for actuating the same, meanscontrolled wholly from the central station for preventing any movement.whatever of such actuating means when desired, and a signaldevicelocated at the central station for indicating to the operator thatan actuation has occurred.

4. In an apparatus for registering telephone calls, a registeringdevice, a reciproeating member for actuating the same, means fornormally locking said member, two circuits, one of which when closed,releases said member, and the other of which the said member closes whenactuated, and a signal in said last-named circuit.

5. A registering attachment for telephones comprising a registeringdevice, a reciprocating member under the control oi the central operatorfor actuating the same, a circuit 6X- tending to the central office andadapted to be closed by complete actuation of said member, and meanscompelling each actuation of said member to be complete, before anotheractuation can occur.

6. A registering attachment for telephones comprising a casing, aregistering device and a spring-retracted plunger under the control 1 ofthe central operator for actuating the same mounted within the casing, acircuit extending to the central oflice and adapted to be closed by acomplete stroke of said plunger, and means for preventing retraction ofsaid plunger upon any incomplete stroke thereof.

7. A registering attachment for telephones, comprising a registeringdevice located at the subscribers station, a reciprocating member forpositively actuating the same, a latch normally locking said memberagainst any movement whatever, means wholly under the control of thecentral operator for with drawing said latch, and an electric signaldevice at the central ofiice, the circuit of which is controlled by saidreciprocating memberv Signed in the city and county of San Francisco,State of California, in the presence of two witnesses, this 30th day ofOctober 1906.
